PSG has now claimed the season-opening cup on 14 different times.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck two times late to take a surprise advantage. Initially, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the twelfth time in the last 13 years.
